Abstract (en)

[origin: DE19625564A1] The invention relates to a fuel supply pump for a fuel injection pump for internal combustion engines, with a driven pair of meshing pinions (7, 9) rotating in a pump chamber (3) which feed the fuel from a suction chamber (13) connected to a tank along a supply channel (17) formed between the faces of the pinions (7, 9) and the peripheral wall of the pump chamber (3) to a pressure chamber (15) connected to the fuel injection pump, and with a channel (25) integrated into the housing (1) of the fuel supply pump and connecting the suction chamber (13) to the pressure chamber (15) which can be controlled by a pressure valve (31) fitted therein, in which the pressure valve (31) is in operative connection with a throttle valve (40, 50) which adjusts the supply of fuel to the suction chamber (13) via the pressure chamber (15) depending on the controlled pressure on the pressure valve (31).
